英文摘要
|
A moment-based approach was applied to the data of Japanese rice-growing farms during 1996-2003 to study the influences of technical progress, weather condition, farm size, conversion policy, ratio of rented land, ratio of capital to labor, and degree of agricultural dependence on the risks of the farms' profits, costs, and production. In order to analyze the structure and contents of farms' risk in a deeper degree, the risks were decomposed into three factors: mean, variance, and skewness. The empirical results show that technical progress, an increase in ratio of rented land and degree of agricultural dependence would increase the mean of profits while a higher level of ratio of land conversion would result in a lower mean of profits. Technical progress, weather improvement, and an increase in the ratio of land conversion would raise the variance of profits; the expansion of farm size, an increase in the ratio of capital to labor, and degree of agricultural dependence would decrease the profit risk.
